Poisson’s ratio is the ratio of transverse contraction strain to longitudinal extension strain in the direction of the stretching force.

Mathematically, Poisson’s ratio is defined as:

ν=

Where:

$ν$ is Poisson’s ratio,
Lateral strain is the change in dimension perpendicular to the applied force,
Longitudinal strain is the change in dimension parallel to the applied force.

The ratio of shear stress to the corresponding shear strain within the proportional limit of the material.

$G$ is the modulus of rigidity in Pascal (Pa),
$τ$ is the shear stress in Pascal (Pa),
$γ$ is the shear strain (dimensionless).

Volumetric strain is a measure of the change in volume of a material subjected to deformation, typically due to mechanical stress. It is defined as the change in volume ( $Δ V$ ) per unit original volume ( $V$ ), and it is dimensionless.

The formula for volumetric strain ( $ϵ_{v}$ ) is:

change in volume ( $Δ V$ )
unit original volume ( $V$ )

SI unit : (Unit Less)

Normal Stress Calculator

Normal stress, often denoted by the symbol σ (sigma), is a measure of the force acting perpendicular to the cross-sectional area of a material.

$σ$ (sigma) is the normal stress,
$F$ is the force acting perpendicular to the surface,
$A$ is the cross-sectional area.
